- Superior deformation control: The vertical configuration allows self-weight sagging to offset part of the thermal deformation. Combined with shape-limiting fixtures and real-time monitoring, overall deformation is significantly lower than that of horizontal machines, making it suitable for high-precision planetary roller screws.
- Strong process adaptability: Dedicated induction coils and soft-zone-free hardening technology are designed to accommodate multi-start and multi-raceway structures of planetary roller screws, ensuring a uniform and continuous hardened layer.
- High level of automation: The hardening machine supports continuous scanning, segmented quenching, and integrated quenching and tempering processes. It delivers excellent consistency in batch production, meeting mass production requirements in industries such as automotive and robotics.
- Data-driven production monitoring: Processing data can be uploaded to the cloud for analysis, enabling real-time monitoring of the production process and improving overall manufacturing efficiency.
